E: Prob still is 'no' in all cases except 'I keep a rare coin collection for speculation purposes'. Saw that the local places which used to accept bitcoin no longer do so.
Memecoins are meant to be unstable and bring no value. It's sad that people get interested by them more than they get interested by Bitcoin, which is a lot more serious and stable
Not meme coins, but stable coins exist - which are tethered to a particular global currency (eg. USD), but their primary/sole purpose is to act as a way to lock in price trades (as actual transfers may not go through instantly and would therefore differ in value otherwise).
The whole crypto currency market is a house of cards. Just some are a bit lower in the structures than the others so don't fall over as often. But in the end, none of it is safe and none of it has a positive economic value.
Someone did some math (an actual paper iirc) on stablecoins, they actually had a mathematical stable value to which it would return, which was around the pegged value. Only one problem, this wasnt the only stable value, as they had 2. The other stable value was 0. Hmm black swans
